Conclusion on classification

Under the DSD, DPGDB is classified as N, R51/53. This results from Acute toxicity to fish, 96h LC50, 3.7 mg/l and Log Pow >3 (3.9).

Under the CLP (EC No. 1272/2008), because DPGDB has Log Pow <4 (3.9) and is readily biodegradable, it was not classified for the environment. However, with the 2nd ATP of the CLP (EU No. 286/2011) the criteria for hazard classification has changed where the classification may be based upon long-term chronic endpoints. Under the revisions from the 2nd ATP of the CLP, the hazard classification of DPGDB is revised effective December 1, 2012 to Chronic Category 3 based upon being readily biodegradable and having adequate chronic toxicity data available indicating a chronic NOEC for the algal of >0.1 to 1.0 mg/L.
